A railway vehicle body (1) swings when cornering about arms (2a, 2b) fixed to the bogie (3) and an instantaneous centre (A). The motion is detected by hydraulic jacks (4a,4b) mounted between bogie and vehicle body and a compensating motion is given to the pantograph (13) through a supporting platform (10) able to move through slides (6a,6b,6c) and driven by slave jacks (8a,8b) |
